Save your Money on Earth Electrodes ……a Case for Copperbonded Steel Earth Rods
Quality earth rods are commonly made from either solid copper, stainless steel or copperbonded steel. The copperbonded steel cored rod is by far the most popular, due to its combination of strength, corrosion resistance, and comparatively low cost. Solid copper and stainless steel rods offer a very high level of corrosion resistance at the expense […]
Why earthing is Vital and what it should be?
Grounding (Earthing) plays a vital role in all electrical systems or infrastructure. It is the number one key power quality (PQ) factor, together with wiring contributes 90% of PQ problems. Proper earthing (grounding) system help resolve power quality issues like Voltage Disturbances, Harmonics, Lightning & Surge Protection, Electromagnetic Interferences and Electrostatic Discharge. All these affect […]
Types of Voltage Disturbances Explained
In Power Quality troubleshooting, voltage disturbances are critical factors. The ability to identify the characteristics and analyze the disturbance is key to the appropriate power quality solution to be deployed. Most often referred as surge (transient overvoltage), while they are not. Today, we shall explain, basically what surges (transient overvoltages) are and what they are […]
ELECTRIC MOTORS AND DRIVES II
85% – 90% of Electric Motors in use for commercial and industrial applications are three phase AC induction motors. The benefits are in their; Simplicity in design Efficiency Ruggedness Costs, low to operate Reliability Adaptability to variable frequency drives (VFDs) Today, we shall review some major characteristics/parameters of Electric Motor like the Efficiency, Loading/Load Factor […]
Performance Wiring and Grounding (Earthing) – Basic Principles II
Nations have Electrical standards & Codes which are the “bibles” for proper grounding. In each country these standards are designed to protect the public from electrical shocks and fire hazards only. It does not deal with the power quality issues. However, there are recommended practices that meet the requirements for performance grounding which mitigate inherent […]
Performance Wiring and Grounding (Earthing) – Basic Principles I
Wiring and Earthing (Grounding) are essential power quality (PQ) tools used in energy management. The use of best practices in wiring and grounding (earthing) ensures safety, prevents fire hazards and importantly allows a piece of equipment to function in its intended manner without significant loss of performance and life expectancy. It improves efficiency and quality […]
Electric Motors and Drives – (I)
Electric motors convert electrical energy into rotational mechanical energy. The motors are either AC or DC powered. Altogether they consume an estimated 50% of global electricity. Electric motors are highly efficient, reliable, offer long lasting service and cost relatively little to maintain. They come in sizes of thousands to fractions of a horsepower (1 HP= […]
Electromagnetic Compatibility (EMC) – The Fundamentals
In certain environments, electromagnetic energy is unintentionally generated, propagated and the reception cause major HSE challenges like noise, discomfort, pollution, affecting performance and physical damage of equipment or systems, injury and even loss of life. Electromagnetic compatibility is concerned with efficient operation and performance of equipment in an electromagnetic environment. The international Electrotechnical Committee (IEC) […]
Power Factor (PF)
Power factor is a critical issue in commercial and industrial establishments. The proper management of power factor for organisations, saves money, enhances operations, extends life expectancy of machinery and saves utility penalties. From the electricity utility perspective it frees up energy for other customers and reduces pressure on electrical infrastructure. It is therefore a power […]
LIGHTNING PROTECTION …an insurance for your assets
Lightning contain awesome amount of electrical energy and even though it is of a very short duration. It leaves behind tremendous damage and destruction. The effects of a direct strike are obvious and apparent – buildings damaged, trees blown apart, personal injuries and loss of life. Lightning can cause fires, explosions, chemical release or mechanical […]
